BEFELL CARTRIDGE FOR LUBRICANT GUNS.

Application filed March 21, 1921. Serial To all "ac/mm may; con ccrn:

Be it known that I, Amrnrr E. Simmons, a citizen of the United States, and resident of Eureka, county of Humboldt, and State of (Ialifornia have invented a new and useful Refill Cartridge for Lubri ant Guns, of which the following is a specification.

My invention while relating in general to lubricant guns has refer nce more particularly to an improved means of introducing; the lubricant into the cylinder of the gun where it may be acted upon by the piston and forced through the discha spout in the customary manner. ii he 1611i feature of the invention resides in an arrangement whereby lubricants for grease guns may be conveniently vended in a package which is suitable for use in combination with the cylinder of the gun for conveniently eifecting a transfer of the lubricant from the pack age to the gun cylinder.

In the accompanying drawing which illustrates the preferred manner of reducing the invention to practice, Figure 1 is a view in side elevation and partly in section of the package which contains the lubricant as it is sold to the trade in accordance with my invention; Figure is a view in side elevation and partly in section of lubricant gun; Figure (3) detail perspective view of the ring member which is employed in connection with the package and Figure 1) is a longitudinal section of a portion of the cylinder of a lubricant gun and the package as cooperating; therewith in effecting a trans for of the lubricant from the package into the gun.

l leferringnow to the drawings in detail (A) represents a lubricant gun which may be of a more or less conventional construetion and inchidingdi charge spout through which the lubricant discharged by pressure exerted by a downward thrust of the piston (C) through the rod (1 and th hand-hold (iii). The cylinder the gun a threaded cap closure (F) which may be removed to open the end of the cylinder and through which the rod (1)) of the piston (C) is free to reciprocate.

As heretofore practiced, lubricant used for these guns is purchased on the market in various kinds of containers and considerable inconvenience is experienced in transferring the lubricant from the container into the gun. It requires not only time but it is extremely dithcult to pack the lubricant in the gun so that a complete charge may be made ready to be acted upon by the piston when pressure is exerted to force the lubricant through the discharge spout (ii).

i-iccording to my invention. these and other disadvantagcs as toipericnced with these heretofore employed means have been entirely overcome and l have provided an extremely simple and convenient means which may be relied upon as a practical solution of the problems involved. .ficcording to the preferred einbcnlinie'nt of my invention I propose to sell the lubricant to the trade in cylii'idrical shaped package neferably, but not necessarily made of h J91 or paper. such as the open ended tube (5). Each of the ends of the tube may be closed by a re1novable cap (6). These packages in reality become so called cartridges and the length of the same may vary according to the amount of the lubricant to be contained therein, but their transverse dimensions must be more or less accurately determined according to the diameter of the grease gun. with which they are to be used. For instance grease guns are made of different diameter, consequently these cartridges will have to be made in different corresponding diainctel the reason for which will presently follov.

In practice when a refill of the lubricant gun is to be made. the cap (F) of the gun is iniscrewed and taken 0d and the piston (C) will he carried thereby and leave the cylinder of the gun with an unobstructed open end. One or the caps preferably that cap which has associated with it the ring is removed and the cartridge presented over the cylinder of the gun so that the some may telescope therew =1. with the ring (7') maintained at the addition of the cylinder to that downward thrust is imposed on. the

to 'telesco iethe same with the cyl- 1. he ring will cut the lulnicant 'roni tie walls of the cartridge so that all ubricant may be properly introduced or transferred into the gun cylinder. The ring; also performs a further function by providing a tight between the cylinder and the cartridge so that none of the lubricant will leak through on the outside of the cylinder. The ring (7) may be made in any desirable form; according to the present showing it is expansible.

I consider this arrangement to be a highly desirable improvement over the old methods employed, especially as the same may be I manufactured. at a comparatively modest cost which will not take away from the com mercial possibilities.

I claim:

A refill for lubricant guns, including a cartridge made to contain a charge of lubricant for the gun, a, removable cap closure for the cartridge, an expansion ring positioned in the cartridge in front of the lubri- ALBERT E. SIMMONS.
